I received your letter dated 2 March and the enclosed statement of account. On checking the statement, I found that a debit entry (4 Jan 19XX for the amount Rs. 1342.65) again does not tally with the invoice (no. 4536) you sent me earlier. Your previous statement also contains the same error.

I have already mentioned this to your representative Mr. James Chong and he promised to look into the matter. But up to now I have not heard anything from him nor has the error been rectified.

I enclose a copy of your invoice. Please check the account again or send someone over to sort out the problem.
